Title: Electrochemical process for fabricating article exhibiting substantial three-dimensional order and resultant article
Inventor: BRAUN PAUL VANNEST
IPC: C30B29/68
Filed: 2000-01-24
Granted: 2003-07-22
Abstract: A structure, e.g., a photonic band gap material, exhibiting substantial periodicity on a micron scale is provided. Fabrication involves the steps of providing a template comprising a colloidal crystal, placing the template in an electrolytic solution, electrochemically forming a lattice material, e.g., a high refractive index material, on the colloidal crystal, and then removing the colloidal crystal particles to form the desired structure. The electrodeposition provides a dense, uniform lattice, because formation of the lattice material begins near a conductive substrate, for example, and growth occurs substantially along a plane moving in a single direction, e.g., normal to the conductive substrate. Moreover, because the electrochemically grown lattice is a three-dimensionally interconnected solid, there is very little shrinkage upon subsequent treatment.

Abstract: A method and an apparatus for handling incoming calls when call waiting is active. If the called party is not on a call when an incoming call occurs and the called party does not answer the incoming call then a message is played to the calling party that the called party did not answer, and the called party is given the opportunity to record a message for the called party. If the called party is on a call when an incoming call occurs and, after the call waiting signal is played to the called party, the called party does not answer the incoming call then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. If the called party is engaged in a first call and a second call when an incoming call occurs then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. Therefore, even when call waiting is active, the calling party is properly advised of the reason that the called party did not answer the incoming call.
